Application Form Integration. Potential for further work

I need an existing "online application form" integrated into one complete form. The form currently has 11 separate sections that need to be combined and executed properly.

Essential requirements:
- Integration of all 11 sections into a single application form.
- Functionality to upload files.
- Option for users to provide a digital signature.

Form submissions should be delivered as email notifications.

Ideal skills and experience:
- Proficiency in online form builders and integrations
- Experience with file upload and digital signature functionalities
- Strong attention to detail to ensure accuracy in form integration

Needs someone with these requirements for ongoing work if applicant is successful:
✅ 1. Frontend (Client-Side)
Purpose Technology Reason
App UI Flutter Cross-platform (iOS + Android) with native performance
Low-code option (optional) FlutterFlow Speeds up UI design; integrates with Firebase
HTML Forms (for Web) HTML5 + TailwindCSS (optional) For digital intake form portals
User Interaction Dart (language of Flutter) Required for app logic, forms, inputs

✅ 2. Backend (Server-Side)
Purpose Technology Reason
Authentication, Database, Storage Firebase (Google Cloud) Secure, scalable, HIPAA-compliant base platform
File Storage (PDFs, images, test results) Firebase Storage (or Cloud Storage buckets) Simple file management
APIs & Webhooks Firebase Cloud Functions (Node.js) For serverless backend logic
AI Recommendations (blood test advice) Python-based API with FastAPI or Flask For calling LLM or ML models
Real-time Alerts & Notifications Firebase Cloud Messaging (FCM) Push alerts to app (e.g. new results, follow-up needed)

✅ 3. Database
Purpose Technology Reason
NoSQL storage Firebase Firestore Lightweight, scalable, ideal for user folders, test history
Structured user metadata JSON storage + Firestore Easy to version and query user data

✅ 4. AI Integration Layer
Task LLM/Service Usage
Report interpretation GPT-4 / Claude / Gemini Pro Recommend tests, explain results
Auto-referral generator GPT-4 / Claude Ability to Drafts letters or summaries
Symptom-to-test mapping Custom-trained ML model Predictive suggestions (hosted via Python API)
User Query Router AI switchboard (e.g. LangChain) Route tasks to best LLM automatically

✅ 5. Security & Compliance
Task Technology Notes
HIPAA/GDPR-compliant hosting Firebase + VPC + HTTPS + Cloud IAM Encryption at rest and in transit
Authentication Firebase Auth + 2FA (phone/email) Secure logins with optional biometric auth
Logging & Monitoring Firebase Monitoring / Google Cloud Logging Track app errors, performance, security events

✅ 6. Other Tools & Platforms
Purpose Tool Use Case
Form Integration (PDF/HTML) JotForm / Form.io / Typeform Optional low-code web intake
Zapier Automation To link Daylite CRM, Gmail, Cloud Storage
Stripe Payment Gateway Subscription + blood test checkout
Cloud Functions Scheduler Firebase Auto-generate reports every month or trigger workflows
